Description

Metallux ME657 monolithic pressure sensors are made with a ceramic cell and work following the piezoresistive principle. Metallux ME657 have a reduced diameter of 12.85 mm. The sensors are thermally compensated by laser-adjustable PTC resistors and offset can be adjusted following customers’ specification. The Wheatstone bridge is screen printed directly on one side of the ceramic diaphragm by means of Thick Film technology. The diaphragm opposite side can be exposed directly to the medium to be measured. Because of the Al2O3 ceramic excellent chemical resistance (aggressive gases, most of solvents and acids, etc.), no additional protection is normally required. Thanks to the reinforced outer area (monolithic structure), the sensor allow easy integration directly in a plastic or metallic case by using O-ring. ME657 sensors are designed in such a way so that temperature changes and pressure overloads do not cause loss in reliability. Use of ceramic ensures high linearity across the entire range of measurement and minimizes effects of hysteresis.
